Compound feed for young soft-shelled turtles and preparation method thereof

Abstract

The invention provides a compound feed for young soft-shelled turtles and a preparation method thereof. The compound feed comprises fish meal, alpha-starch, fermented soya bean meal, fish oil, yeast, methionine, lysine, milk powder, yolk powder, composite mineral premix for feed of the soft-shelled turtles, composite vitamin premix for the feed of the soft-shelled turtles, calcium dihydrogen phosphate, an enzyme preparation and a Chinese medicinal additive. The preparation process comprises the following steps of: feeding; cleaning for the first time; mixing for the first time; removing iron; pulverizing; mixing for the second time and packaging. The compound feed and the preparation method thereof have the advantages of improving disease resistance of the young soft-shelled turtles, selecting high-digestibility feed raw materials, increasing conversion rate of the feed, reducing the emission of pollutant of nitrogen, phosphorus and the like, reducing pollution of culture water, reducing disease of the young soft-shelled turtles, reducing the using amount of pesticide, meeting the requirement of ecologic cultivation at last, increasing adsorption and utilization rate, meeting the nutritional requirement of the young soft-shelled turtles, reducing cultivation cost, and reducing pollution on water, along with scientific and reasonable formula, scientific and reasonable preparation method and obvious economic benefit and environmental benefit.

Description

Technical field [0001] The invention belongs to the field of feed technology, and more specifically relates to a compound feed for young Chinese soft-shelled turtles. Background technique [0002] Chinese soft-shelled turtle ( TrionyxSinensis ) Commonly known as soft-shelled turtle, Yuanyu, Tuanyu, Shuiyu, Wangba, etc. In animal taxonomy, it belongs to the phylum Vertebrates, Reptiles, Turtles, Turtles, and Turtles. There are more than 20 species and subspecies in this genus (there are only 2 genera and 3 species of Trionyx in China, 1 species of Turtle genus, 2 species of Turtle genus, Trionyx sinensis and Trionyx sinensis), all of which are produced in temperate and subtropical Asia. Soft-shelled turtle has been favored by people since ancient times for its nutritional, high medicinal value and delicious taste, and has been popular in domestic and foreign markets. Due to the sharp decline in natural turtle sources, the contradiction between supply and demand has become increa...

Problems solved by technology

However, high-input, high-yield, high-tech factory breeding of soft-shelled turtles has certain risks. If the daily management is not in place and the selection of compound feed is improper, it is likely to cause frequent soft-shelled turtle diseases and high mortality.

In addition, after many soft-shelled turtles are fed with feed, the soft-shelled turtles do not like to eat, there are many residues, the conversion rate is low after feeding, and a large amount of nitrogen and phosphorus are emitted, which causes serious pollution of the breeding water, causing the prevalence of soft-shelled turtle diseases and serious death

Some farmers use a large amount of drugs for unscientific disease prevention and control. As a result, the drug residues in commercial soft-shelled turtles seriously exceed the standard, endangering the health of consumers. In recent years, there have been frequent incidents of toxic aquatic products in my country, all of which are caused by the indiscriminate use of drugs.
